A useful example is to use it as AND
filters when combined with where:
AND filter in where query
{{ $pages := where .Site.RegularPages "Type" "not in" (slice "page" "about") }}
{{ $pages := $pages | union (where .Site.RegularPages "Params.pinned" true) }}
{{ $pages := $pages | intersect (where .Site.RegularPages "Params.images" "!=" nil) }}
The above fetches regular pages not of page
or about
type unless they are pinned. And finally, we exclude all pages with no images
set in Page params.
See union for OR
.
